SECTION FOR AUTOIEOBILE-RADIATORS.

To all whom it may concern:

Be it known that I, HUGO Ktin'rzxnn, av citizen of the Ynited States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Sections for iutomobile-Radiators; and I do hereby declare the following, when taken in connection with the accompanying drawings and the numerals of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, iii- Figure l a broken perspective view of a portion of a radiator-section constructed in accordance with my invention. Fig. 2 a broken view in elevation on an enlarged scale showing the relative arrangement of the corrugated and shouldered plates before their shouldered edges are dipped in solder. Fig. 3 a broken view in vertical section showing the tortuous water-passages formed between the plates placed back to back. Fig. l a sectional view on the line a& of Fig. 3. Fig. 5 a broken plan view of one of the plates in correct scale.

My invention relates to an improvement in sections for automobile radiators, the object being to provide a light, cheap, strong and effective section.

With these ends in view my invention consists in a radiator-section having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

In carrying out my invention I place one upon the other in a predetermined order of arrangement, a number of thin sheetmetal transversely corrugated plates the semi-circular or substantially semi-circular corrugations 2 of which terminate at their ends in corresponding shoulders 3 struck on slightly larger circles than the corrugations. These plates are assembled face to face in pairs so as to form horizontal tubular air-passages a between the concave faces of the plates and tortuous vertical contracting and expanding water-passages 5 between the convex faces of the plates as clearly shown in Fig. 3. The said water-passages 5 are included between the said shoulders 3 which rest upon each other as shown in Fig. 2, and so prevent the convex faces of the plates from making con tact with each other in the narrow portions 6 of the water-passages 5 which are so tortuous that the water will pass through them Specification of Letters Patent.

so slowly that it will be exposed for a considerable length of time for the cooling effect of air passing through the air-passages it. It will be observed by reference to Figs. 2 and 3 that in assembling the plates they are placed face to face in pairs, but that every alternate pair is moved upward or downward with respect to the adjacent pair, for a distance substantially represented by half the diameter of the air-passages. In other words, the plates are staggered with reference to each other, in pairs so as to secure compactness of construction and to form tortuous passages for the water. 2* fter the plates have been properly assembled their el 'es will be united by a binder of solder 7 which unites the plates together in a laminated cellular structure.

My improved construction is not only light and cheap, but also extremely strong as the transverse corrugations of the plates make them stiff and resistant of blows tending to crush them. If desired the plates may be swaged after they have been assembled and soldered together by the introduction of hexagonal swaging tools, the use of which will give the section the appearance. of a honeycomb.

I claim A section for automobile radiators, the said section being composed of a number of independently formed transversely corrugated sheet-metal plates each extending from the top to the bottom of the section and each formed upon each edge with a continuous shoulder slightly larger than the corrugations, and the said corrugations and shoulders being circular in form, the plates being symmetrically assembled face to face in pairs so as to form circular horizontal air passages. the pairs being assembled unsymmetrically so as to form tortuous vertically arranged contracting and expanding waterpassages between the convex faces of the plates which are held apart for the formation of these passages by means of the said shoulders, and the edges of the corrugations and hence the plates being bound together by a continuous sheet of solder.

In testimony whereof, I have signed this specification in the presence of two subscril ing witnesses.
